best trailer for a Brompton?
 

There's been other posts over the years, but what's available to buy has changed. So I thought I'd see what the current collective wisdom is: which trailer hitches work best on a Brompton? It'd be cool to be able to do the parking/kickstand wheel fold with the trailer on, but that's not really a requirement as I'd need to detach it to lock up anyway. It just needs to not interfere with the fold at all when the trailer is detached, and not stick out in a way that the bike wider when folded.

And I want something a little easier to load with multiple floppy canvas shopping bags than the travois-style seatpost-mount trailers.

I've been haunting my local craigslist for beat-up kid trailers I could tear down and DIY, but nothing has appeared, so if I'm going to pay retail I want to be fairly sure about what I'm getting.

(I'm in the US, so it needs to be something with an established US dealer.)

I would think it's good to look into Burley Travoy or Carry Freedom (I wanted to buy the City but can't find it anymore). Most popular probably.

This is my home built trailer. Since the pictures the tires have been replaced with slicks. The folder in the pictures is what it is pulled with. I use it for getting the mail and going to the store. The box is Rubbermaid and comes in bigger sizes. Roger

Yeah, I guess I shouldn't have put as much info. I'm specifically asking which companies' hitches people have used on their Bromptons and found not to interfere with the size of the folded bike.

And which, if any, will do the wheel-tuck fold so that I wouldn't have to hold the bike upright while detaching the trailer.

What works best on a Brompton, would have to be seat post mounted. The Burley Travoy works just fine. I have both, Brompton and Burley.

Check out this YouTube video.

Also if you could find an old Cannondale Bugger, either one that carries kids or the cargo trailer, they would both work. Cannondale trailers haven't been sold for maybe decades but used ones occasionally pop up.

I like the Chariot (now a Thule brand) hitch .. It uses a ball elastomer , in a socket hitch under the left axle Nut.

Because It being a Ball, when the rear fold is done , it rotates the Hitch around the ball ..

Minus the QR skewer ...safety strap optional.


I got a Carry Freedom City.. Bike trailer shop in AZ had them, then, but opted out of ordering more when the UK company changed the terms.

It is a perfect match for Bromptons . it folds flat within it's own frame. (has rear edge rollers to slip it, vertically, between back to back train seats too)
+ because tow bar/handle, comes in at a right angle to the bike, the Ball elastomer hitch rotation works perfectly ..

and you can carry the folded up bike on top of the trailer. Say you have to run the length of the platform to your seat on the train..

Thanks. The travois-style trailers on the market right now are way smaller than I need -- the Travoy is the biggest I've found and it's tiny in terms of carrying bulky stuff, but if I was going to DIY I could try using their hitch. Though I'm curious how does a seatpost mount not interfere with the fold? The seatpost on mine has to go all the way down to lock correctly.

If you have the Brompton Extended Seat Post, rather than the shorter standard length,

you could clamp the Hitch above the part that goes into the Frame , when you fold the Bike..




I leave the Chariot hitch under the axle nut , it is not in the way when folded, at all ..

I'm fairly short, so I have the regular seatpost. :) But thanks -- that's very helpful. I'll take a look at the Chariot trailers.

I think I'll just give up on wanting to be able to fold it under -- that was kind of just a bonus as I'm not going to be taking the trailer on the train with me -- the trailer would only be for rare occasions when I need to haul a lot of bulky cargo. I just wanted to pick out a trailer that would work with all my bikes, and the Brompton is the only one that's unusual.

Just that the rear fold under is like a Kickstand .
as long as the seat post goes down as far as the stop disc on the forward end of the rear brake Bolt,
the rear wheel will not unfold, when you lift the folded up bike.


this is their version of the Carry Freedom 'Y' trailer.

with a Platform, Or adding a box like the Rubbermade shown above, 3rd post.

I see their lowest price Kid Trailer is for the moment reduced, on that site https://www.bikekidshop.com/thule-ch...e2-p-3491.html

The seat doesn't need to be all the way down to lock the bike as you can see from the photos. What do you plan to carry on the trailer you want?

Check out this video on Brompton and the Radical Design Chubby that Fietsbob mentioned.

Nice, but 450 quid?

I would have thought that Extrawheel would have been ideal for your needs.

They supply either a QR of the correct length or specially-shaped axle nuts and the yoke is then fixed to these. No addition to the width in each case.

I would have thought that the trailer being under eight pounds would be an advantage also and it means that normal panniers can be used.

Have you ^^ Tried an ExtraWheel with a 16" Front Wheel in it?

Not yet I haven't but I was thinking of trying one with my 20" wheel Moulton.

I take it there are problems......do tell.

New version has a pannier support frame .. which has a Bottom

'they ship with 26/or 700 wheels.

406-47 ought to work ..

However, please be aware that:
If your bicycle trailer wheel is smaller than 20", the load or panniers may rub against the ground.
The Extrawheel frame can support all bike pannier models, including those from other manufacturers.
